ARI SAFE P 12.921 Proportional Lift Safety Valve PN16 DN32
Controlled proportional lift protects pressurized systems from sudden pressure surges.
The ARI SAFE P 12.921 Safety Valve protects pressurized systems by preventing sudden discharges and providing controlled relief. In addition, its EN-JL1040 cast iron body and stainless steel internal parts withstand temperatures up to 300 °C. Furthermore, it enhances safety particularly in steam boilers and process lines.
When system pressure exceeds the set point, the valve opens proportionally and discharges the excess pressure. Moreover, the spring mechanism reacts precisely, which prevents unnecessary discharges. In addition, the stainless steel disc and seat materials provide superior corrosion resistance, therefore enabling a long service life.
